Electricity exports from the Western Balkans to the European Union are increasingly linked to whether importers can demonstrate the origin, emissions profile and contractual traceability of delivered power. For independent power producers, trading companies and EU importers, substantiating actual embedded emissions is becoming a factor in cross-border electricity transactions.
CBAM scope for imported electricity under customs code 2716 00 00
The EU’s Carbon Border Adjustment Mechanism (CBAM) entered its definitive phase on 1 January 2026, covering imported electricity under customs code 2716 00 00. Electricity imports have no equivalent mass-based exemption to the 50-tonne annual threshold that applies to certain industrial goods. The EU entity responsible for an electricity import must determine applicable CBAM declaration and certificate obligations regardless of volume or delivery profile.
A distinction applies between electricity assessed using the applicable country default emissions factor and electricity for which an authorised EU CBAM declarant can demonstrate actual embedded emissions. The actual-emissions approach can be relevant to wind, solar and hydropower producers, subject to meeting applicable requirements. Under rules described as applicable in October 2026, the process includes a qualifying power purchase agreement, transmission-system evidence, emissions eligibility, firm hourly nominations and independent verification.
Renewable energy certificates, trader invoices or general declarations that electricity comes from a green installation cannot independently replace those requirements. The documentation set is therefore tied to the ability to support actual embedded emissions through the specified elements.
Trading volumes and day-ahead price gaps across EU and Western Balkans borders
The Energy Community Secretariat reported that commercially scheduled electricity trade across EU–Western Balkan borders declined by 25% in the first quarter of 2026. In the same period, average day-ahead electricity prices in the Western Balkans were approximately €30/MWh below prices in neighbouring EU markets. The reported gap reflected conditions affecting how cross-border transactions could be structured.
A report indicated that conventional arbitrage opportunities became more difficult to monetise even when electricity was available at lower prices in the Western Balkans. A second-quarter report recorded a partial recovery in cross-border flows, while renewable generators continued to face difficulties documenting actual emissions.
Contracting structures for producers and trading houses
Independent power producers are required to assess whether to sell into local wholesale markets, conclude domestic industrial PPAs, or allocate output to a specifically identified EU importer under a more detailed contractual arrangement. Electricity sold through several successive traders may still be traded and delivered operationally, but a conventional chain of resales does not necessarily meet requirements for recognition of actual emissions.
A direct PPA between the producer and the authorised EU CBAM declarant provides a clearer contractual starting point. A carefully structured tripartite agreement involving an intermediary is another possible arrangement for linking contractual roles to CBAM documentation needs.
For trading houses, the issue concerns how commercial activities align with contractual responsibilities. Their established functions include aggregating purchases, managing congestion rights, optimising positions across exchanges and selling flexible delivery products; CBAM does not remove those functions but requires traders to distinguish whether they act as a commercial principal, a nominated intermediary or a provider of scheduling and balancing services.
These roles must correspond to parties’ actual legal obligations rather than relying solely on contract terminology used in documentation.
CBAM certificate pricing and implications for import economics
The financial implications are linked to the price of CBAM certificates. The official certificate price for the third quarter of 2026 was €82.32 per tonne of CO₂e, up from €75.28/tCO₂e in the second quarter.
Using a hypothetical default exposure of one tonne of CO₂e per MWh, gross carbon cost would exceed €82/MWh before any applicable statutory adjustment. Under that assumption, an ordinary transmission-cost or wholesale-price differential would not be sufficient to sustain an import margin.
The calculation is illustrative rather than a universal charge on imported electricity. Actual liability depends on the legally applicable emissions value and other relevant regulatory provisions.
Lender assessments and contract clauses supporting traceability
Lenders evaluating renewable energy projects designed around electricity exports to the EU need to assess more than signed offtake agreements and projected baseload or capture prices. They must consider which delivery volumes can qualify for actual-emissions treatment and how much generation could instead fall under default emissions values.
Other factors include allocation of costs when eligibility is lost, project resilience to interruptions in cross-border transmission capacity, and consequences of an adverse verification finding. A long-term PPA may provide weaker financial security if expected premium levels for renewable electricity cannot be substantiated under applicable CBAM requirements.
Electricity export contracts need to distinguish between physical energy price, balancing and transit charges, data-delivery obligations, carbon-cost adjustments and remedies for failures in supporting evidence. Responsibilities should be allocated according to parties’ functions: the generating installation operator for metering records, the relevant market participant for nominations, and the authorised EU CBAM declarant for final CBAM declarations.
Contracts should also address changes in legislation. EU institutions are discussing more flexible rules for electricity imports, but measures described as applicable remain under debate and have not yet been enacted; any contractual mechanism addressing such changes must distinguish existing legal obligations from potential future amendments.
For producers and traders operating between the Western Balkans and the EU, the commercial challenge is connecting renewable generation with deliverable electricity volumes, legally traceable transactions and independently verified emissions data. Establishing that connection is becoming an important consideration for securing and maintaining access to EU electricity markets.
